Major achievement

Major Achievement

  • 使用分光鏡及兩組以上不同特性CCD (Charge-Coupled Device)攝影機之取像裝置

    • 提高待檢物件之取像品質;藉由了解各種欲檢測之項目或特徵,而使用不同特性之CCD攝影機予以讀取之

  • 檢測圓形物件之照明裝置

    • 僅使用一組可自動調整亮度之環形光源即達成對物件表面之多種照明模式,使欲檢測之項目或特徵更為明顯

Major achievement1

Major Achievement

  • 光碟片裂片檢查裝置-專利申請中

    • 運用特殊之光源裝置,使光碟片中心孔處之裂紋由高解析度CCD偵出

    • 可裝在CD-R (Compact Disc-Recordable )前段製程中印刷機處分檢機上

  • 光源亮度自動調整、光碟片由機械手抓住下也能偵測

    • 以自行開發之軟體程式,使待測物件之照明裝置的亮度自動調整至最佳取像品質

Evledc

EVLEDC

  • LED Dice Counter System

DC & CV Lab.

NTU CSIE


Function

Function

  • This system can correctly count the amount of LED (Light Emitting Diode) chips in the inspection area

  • It can improve the exact amount of LED CHIP shipment for LED makers

DC & CV Lab.

NTU CSIE


Major features

Major Features

  • Suitable for counting diverse LED dice without changing the light source

  • Suitable for counting the LED with bounding-pad (transparent) and without bounding-pad (un-transparent)

  • Use high-resolution camera with top light to snap the image (Back lighting module can be selected depending on products)

DC & CV Lab.

NTU CSIE


Major features1

Major Features

  • Countable LED dice arrangement

    • Dice which are already sawed and expended, but do not attach to a wafer ring

    • Dice which are already sawed, expended, and adhered to the paper

    • Dice which are sorted by chip sorter and adhere to the paper

DC & CV Lab.

NTU CSIE


Major features2

Major Features

  • If dice are already adhered to the blue tape, it doesn't need to remove the blue tape when counting. It can prevent the damages caused by the re-attached process, such as decrease of dice number, deviation of dice position, static and so on.

  • As long as the product is within the detection area, it can be counted with no limitations in angles or positions.

DC & CV Lab.

NTU CSIE


Major features3

Major Features

  • Set up individual parameters to detect different products. It only needs a simple "click" to change the parameters.

  • The brightness of light source can be set depending on products and becomes product's parameter.

Major features4

Major Features

  • Bilingual user interface (Chinese/English) which can be switched on-line

  • Input / Output the counting record in a customized format or upload the data to databases by connecting the server (Depend on need)
